We have studied the consequence of different functionalization types onto the decoration of multi-wall carbon nanotubes (MWCNTs) surface by nanoparticles of bismuth and nickel oxides. Three organic molecules were considered for the functionalization: 5-amino-1,2,3-benzenetricarboxylic acid, 4-aminobenzylphosphonic acid and sulfanilic acid. Nanotubes modification with in situ created diazonium salts followed by their impregnation with suitable salts [ammonium bismuth citrate and nickel (II) nitrate hexahydrate] utilizing infrared (IR) irradiation was found the crucial stage in the homogeneous impregnation of functionalized CNTs. Furthermore, calcination of these samples in argon environment gave rise to controlled decorated MWCNTs. The currently used technique is simple as well as effective. The synthesized materials were characterized by XPS, PXRD, FESEM, EDX, HRTEM and Raman spectroscopy. Bismuth oxide decorations were successfully performed using 5-amino-1,2,3-benzenetricarboxylic acid (particle size ranges from 1 to 10 nm with mean diameter ~ 2.4 nm) and 4-aminobenzylphosphonic acid (particle size ranges from 1 to 6 nm with mean diameter ~ 1.9 nm) functionalized MWCNTs. However, only 4-aminobenzylphosphonic acid functionalized MWCNTs showed strong affinity towards oxides of nickel nanoparticles (mainly in hydroxide form, particles size ranging from 1 to 6 nm with mean diameter ~ 2.3 nm). Thus, various functions arranged in the order of their increasing anchoring capacities are as follows: sulfonic < carboxylic < phosphonic. The method is valid for large-scale preparations. These advanced nanocomposites are potential candidates for various applications in nanotechnology.

“…This method has become the standard for creating PPy electro sensing layers due to its ease of use and the high quality of the thin films produced. Given the importance of adhesion, coupling agents may be required to ensure a strong electrode‐PPy bond and prevent delamination of the thin layer of conductive polymer 26 …”

“…Given the importance of adhesion, coupling agents may be required to ensure a strong electrode-PPy bond and prevent delamination of the thin layer of conductive polymer. 26 In electrochemistry, applying a known current through the electrochemical cell and a well-defined potential effectively controls the morphology and thickness of the deposited layer. 27 Some appealing characteristics of electrochemically produced PPy include its strong adherence to the underlying electrode and high conductivity.…”

As metal ion inclusion has a substantial effect on conducting polymer's mechanical, optical, and electrical properties, it has attracted a lot of attention. This article delves into the complex role of metal ions in conducting polymers, explaining how they affect functionality, structural stability, and conductivity enhancement. The review starts with a synopsis of conducting polymers and doping processes before diving into the particular ways that metal ions interact with polymer matrices to alter their electronic structure and charge transport characteristics. The importance of characterization techniques in comprehending the structure–property correlations is highlighted in the discussion of metal‐ion doped conducting polymer studies. In addition, the paper looks at the uses of conducting polymers doped with metal ions in numerous sectors, including energy storage, electronics, and sensors. The difficulties in attaining accurate control over doping concentrations and guaranteeing stability over an extended period are discussed, as well as potential avenues for future development in this area. This review offers important insights into the development and optimization of functional materials for a variety of applications by thoroughly investigating the function of metal ions in conducting polymers.
